Is E621 (Monosodium Glutamate) halal?
E621 (MSG / Monosodium Glutamate) is Mushbooh — its status depends on production origin. In the UK, US, and Canada, MSG is fermented from plant sugars (sugar cane or corn) and is widely considered halal. A 'suitable for vegetarians' label or halal/kosher certification confirms plant-sourced production. Avoid MSG from countries where pork-based fermentation media has been reported unless the product is certified.
